CVG previews StarCraft II, part one

In 1998, StarCraft told the story of three races in conflict, and it went a little something like this... The Terrans - human colonists - are torn apart by civil war and find themselves stuck in the middle of a war between the Protoss and the Zerg. The Protoss and the Zerg are enhanced alien races given an evolutionary leg-up by a meddling super-race called the Xel'Naga.
